Why Tax-Compliant Billing Matters
Tax compliance is not optional. A business that issues invoices without proper GST or sales tax breakdowns can face penalties, failed audits, and payment disputes with customers who need tax-compliant receipts.
Most small businesses use a separate accounting or billing tool for this. Timeline POS builds tax-compliant billing into the point-of-sale itself — so every receipt is automatically correct.
How GST Works in Timeline POS
Configuring Your Tax Rate
When you set up Timeline POS, you configure your tax rate in Settings. This can be a single GST rate applied to all products, or different rates applied to different product categories.
Once configured, the tax rate applies to every transaction automatically.
Tax-Inclusive vs Tax-Exclusive Pricing
Timeline POS supports both pricing models:
- Tax-inclusive: The product price already includes GST. The receipt shows the price and extracts the tax amount.
- Tax-exclusive: The product price is before GST. Tax is added at checkout. The receipt shows product total + tax = final price.
Configure this once in settings based on how your business displays prices.
The Billing Screen

The billing screen shows a live breakdown as you add products: subtotal, tax amount, and total. Customers see exactly what they are paying in tax — which is required in most markets.
Discounts applied to products reduce the pre-tax amount, and the tax recalculates automatically.
Receipts With Full Tax Breakdown
Every receipt generated by Timeline POS shows:
- Business name and tax registration number
- Products sold with individual prices
- Subtotal before tax
- Tax amount (with rate)
- Total amount due
- Payment method
This format meets the requirements for a valid tax invoice in most markets.
Tax Reports for Filing

At the end of each tax period, the POS report shows total sales and total GST collected. This is the input your accountant needs for your tax return — no manual extraction required.
